The ‘Zelle Fraud’ Scam: How it Works, How to Fight Back

This post was originally published on this siteOne of the more common ways cybercriminals cash out access to bank accounts involves draining the victim’s funds via Zelle, a “peer-to-peer” (P2P) payment service used by many financial institutions that allows customers to quickly send cash to friends and family. Naturally, a great deal of phishing schemes that precede these bank account takeovers begin with a spoofed text message from the target’s bank warning about a suspicious Zelle transfer. What follows is a deep dive into how this increasingly clever Zelle fraud scam typically works, and what victims can do about it. […]

SMS About Bank Fraud as a Pretext for Voice Phishing

This post was originally published on this siteMost of us have probably heard the term “smishing” — which is a portmanteau for traditional phishing scams sent through SMS text messages. Smishing messages usually include a link to a site that spoofs a popular bank and tries to siphon personal information. But increasingly, phishers are turning to a hybrid form of smishing — blasting out linkless text messages about suspicious bank transfers as a pretext for immediately calling and scamming anyone who responds via text. KrebsOnSecurity recently heard from a reader who said his daughter received an SMS that said it […]

‘Tis the Season for the Wayward Package Phish

This post was originally published on this siteThe holiday shopping season always means big business for phishers, who tend to find increased success this time of year with a lure about a wayward package that needs redelivery. Here’s a look at a fairly elaborate SMS-based phishing scam that spoofs FedEx in a bid to extract personal and financial information from unwary recipients.

The ‘Groove’ Ransomware Gang Was a Hoax

This post was originally published on this siteA number of publications in September warned about the emergence of “Groove,” a new ransomware group that called on competing extortion gangs to unite in attacking U.S. government interests online. It now appears that Groove was all a big hoax designed to toy with security firms and journalists. “An appeal to business brothers!” reads the Oct. 22 post from Groove calling for attacks on the United States government sector. Groove was first announced Aug. 22 on RAMP, a new and fairly exclusive Russian-language darknet cybercrime forum. “GROOVE is first and foremost an aggressive […]

This post was originally published on this siteThe U.S. Federal Communications Commission (FCC) is asking for feedback on new proposed rules to crack down on SIM swapping and number port-out fraud, increasingly prevalent scams in which identity thieves hijack a target’s mobile phone number and use that to wrest control over the victim’s online identity.

The Rise of One-Time Password Interception Bots

This post was originally published on this siteIn February, KrebsOnSecurity wrote about a novel cybercrime service that helped attackers intercept the one-time passwords (OTPs) that many websites require as a second authentication factor in addition to passwords. That service quickly went offline, but new research reveals a number of competitors have since launched bot-based services that make it relatively easy for crooks to phish OTPs from targets. An ad for the OTP interception service/bot “SMSRanger.” Many websites now require users to supply both a password and a numeric code/OTP token sent via text message, or one generated by mobile apps […]

The Airtag’s “Lost Mode” lets users alert Apple when an Airtag is missing. Setting it to Lost Mode generates a unique […]

Does Your Organization Have a Security.txt File?

This post was originally published on this siteIt happens all the time: Organizations get hacked because there isn’t an obvious way for security researchers to let them know about security vulnerabilities or data leaks. Or maybe it isn’t entirely clear who should get the report when remote access to an organization’s internal network is being sold in the cybercrime underground. In a bid to minimize these scenarios, a growing number of major companies are adopting “Security.txt,” a proposed new Internet standard that helps organizations describe their vulnerability disclosure practices and preferences.
